The '''American Simplex''' was an American [[Car|automobile]] manufactured in [[Mishawaka, Indiana]], from 1906 to 1915 by the '''Simplex Motor Car Company'''; the company shortened its product's name to '''Amplex''' in 1910 to avoid confusion with the better-known, New York-based Simplex car, made by the Simplex Automobile Company. This change also coincided with a reorganization of the company. Originally the company manufactured a [[two-stroke]] [[four-cylinder]] 50[[horsepower|hp]] at 900 rpm from 6435 cc with 127 mm bore and 127 mm, later upsized to 6.8 liters and still rated at 50&nbsp;hp. 
The top speed was 97 km/h (60 Miles per Hour). The wheelbase was 117 inches = 2972 mm. The gasoline tank held 20 gallons = 76 liters<ref>{{cite web|url= https://babel.hathitrust.org/cgi/pt?id=mdp.39015069975962&seq=32 |title= American 30/50 Hp |date=1910-01-01|publisher= American Simplex |access-date=2025-05-01}}</ref>. In 1910, three open-roof models and two enclosed models were offered, costing up to $5,400; the newly introduced 30/50&nbsp;hp Toy Tonneau, a long, sleek four-door touring car, sold for $4,300. The Amplex's most distinctive feature was its valveless motor, which the company claimed would offer more continuous pulling power and greater reliability. The 1910 models also offered self-starting, a feature that would not be available from major competitors, such as Cadillac, for another year or two.<ref>Floyd Clymer, Historical Motor Scrapbook Number Four, (1952), p.80</ref>

They were expensive cars, a limousine being offered at as much as $5,600. Yet the firm kept using the two-stroke engine after it had become obsolete; a four-stroke was offered unsuccessfully in 1913. Gillette Motor Co took over the Amplex manufacturing facilities in 1916, but refused to manufacture conventional engine-valving, persisting with a rotary [[sleeve valve]] engine.
